My setup:
-Raspberry Pi 4, ethernet connected
-HA boots from an external SSD
I had the following problem on my HA
I’m able to turn lights off/on in Lovelace
But unable to go into any settings menu (unfortunately I don’t recall what the exact error was, but no screen loaded)
So I power cycled my Pi4, as I could not go into the settings menu to reboot.
Then, I saw that both lights were on and static. Which indicated a boot issue. I couldn’t ping the HA instance.
After trying a bunch of things, I moved over the SSD to the black USB ports. This finally worked.
In conclusion,
the USB3 (blue) ports don’t seem to be able to boot up HA. Both of them.
And the other USB ports are fine and HA is running as usual.
How do I troubleshoot this?
/ Does this mean the USB3 ports are fried?
/ How do I verify this?
/ Would there be something useful in HA logs? How do I see this?
The pi 4 USB ports are low power output & generally have trouble supplying high power devices like hard drives and some solid state drives.
You can try to use a powered hub or perhaps enable max current for the USB ports on the pi
Also confirm that you got a good input power source.
Hope this helps
Best regards.
